Publication number: 20200142575Abstract: In part, the disclosure relates to intravascular data collection systems and the software-based visualization and display of intravascular data relating to detected side branches and detected stent struts. Levels of stent malapposition can be defined using a user interface such as a slider, toggle, button, field, or other interface to specify how indicia are displayed relative to detected stent struts. In addition, the disclosure relates to methods to automatically provide a two or three-dimensional visualization suitable for assessing side branch and/or guide wire location during stenting. The method can use one or more a computed side branch location, a branch takeoff angle, one or more stent strut locations, and one or more lumen contours.Type: ApplicationFiled: June 18, 2019Publication date: May 7, 2020Applicant: LightLab Imaging, Inc.Inventors: Ajay Gopinath, Denis Dion, Christopher E.

Patent number: 10529093Abstract: In part, the disclosure relates to methods of guidewire detection in intravascular data sets such as scan lines, frames, images and combinations thereof. Methods of generating one or more indicia of a guidewire in a representation of blood vessel are also features of the disclosure. A carpet view is generated in one embodiment and regions of relatively higher contrast are detected as candidate guidewire regions. In one embodiment, the disclosure relates to selective removal of guidewire segments from a set of intravascular data and the display of a representation of a blood vessel via a user interface. Representations of a guidewire can be toggled on and off in one embodiment.Type: GrantFiled: September 28, 2018Date of Patent: January 7, 2020Assignee: LIGHTLAB IMAGING, INC.Inventors: Christopher E.

Publication number: 20190326097Abstract: A microwave plasma chemical vapor deposition device for diamond synthesis. A microwave source generates a microwave signal, and a resonant cavity receives a plurality of process gases. The microwave signal is spread in a first mode at a first waveguide. A mode conversion antenna converts the first mode of the microwave signal into a second mode that is spread at a second waveguide. A coupling conversion cavity receives and transmits the microwave signal in the second mode to the mode conversion antenna thereby converting the second mode of the microwave signal into a third mode. A medium viewport receives the microwave signal in the third mode and transmits to the resonant cavity which enables the microwave signal to excite and discharge the process gases to form spherical plasma, carbon containing groups and atomic hydrogen thereby depositing a diamond film on a seed.Type: ApplicationFiled: April 22, 2019Publication date: October 24, 2019Inventors: Yi Ma, Matthew L. Scullin, Jinhua Zhu, Jianxin Wu, Yong Miao, Di Lu, Yonggan Ai, Christopher E. Griffin

Patent number: 10453190Abstract: In part, the disclosure relates to shadow detection and shadow validation relative to data sets obtained from an intravascular imaging data collection session. The methods can use locally adaptive thresholds and scan line level analysis relative to candidate shadow regions to determine a set of candidate shadows for validation or rejection. In one embodiment, the shadows are stent strut shadows, guidewire shadows, side branch shadows or other shadows.Type: GrantFiled: November 22, 2016Date of Patent: October 22, 2019Assignee: LIGHTLAB IMAGING, INC.Inventor: Christopher E.

Publication number: 20190220980Abstract: The disclosure relates, in part, to computer-based visualization of stent position within a blood vessel. A stent can be visualized using intravascular data and subsequently displayed as stent struts or portions of a stent as a part of a one or more graphic user interface(s) (GUI). In one embodiment, the method includes steps to distinguish stented region(s) from background noise using an amalgamation of angular stent strut information for a given neighborhood of frames. The GUI can include views of a blood vessel generated using distance measurements and demarcating the actual stented region(s), which provides visualization of the stented region. The disclosure also relates to display of intravascular diagnostic information such as indicators. An indicator can be generated and displayed with images generated using an intravascular data collection system. The indicators can include one or more viewable graphical elements suitable for indicating diagnostic information such as stent information.Type: ApplicationFiled: October 22, 2018Publication date: July 18, 2019Applicant: LightLab Imaging, Inc.Inventors: Sonal Ambwani, Christopher E. Griffin, James G. Peterson, Satish Kaveti, Joel M. Friedman

Patent number: 10282940Abstract: Various example embodiments are directed to a computer-implemented gaming management system for facilitating applications that support user wagering. The gaming management system may comprise a computer system in communication with a developer computer device. The computer system may be programmed to receive from the developer computer device configuration data for a contingent event to be associated with a user application; determine whether the configuration data meets at least one predetermined standard; and provided that the configuration data meets the at least one predetermined standard, provide the developer computer device with an application program interface (API) credential to be utilized by the user application, wherein the API credential is to give the user application access to an API for resolving the contingent event.Type: GrantFiled: May 6, 2015Date of Patent: May 7, 2019Assignee: Collisse Group LimitedInventor: Christopher E.
